To all when: it may concern:

Be it known thatiI, WILLIAM C. Srnvnns, a citizen of the United States,and a resident of the city of Akron, in the county of Summit and Stateof Ohio, have invented certain new and useful Improvements inWrapping-Machines; and I do hereby decl are that the following is afull, clear, and exact deseri tion of the same, reference being had to t1e accompanying drawin s, and to the numbers of reference marked tereon, which form' a part of this specification.

This invention relates more particularliy to a machine for spirallywrapping or wm ing a covering strip, such as paper, about annularbodies, for example, automobile tires, and coded wire and the like,or,of course, to afford a spirally wound wrapping about polished pipe,rods, or any other object capable of receiving such a wrapping.lcretofore, practically all, or a large part of such wrapping, has beendone by hand, and, in conse name, the expense for such wrapping has wonunnecessarily la rge,-a nd the wrappings have not been applied with suchuniformity as to present a pleasing appearance, nor sniliciently well sothat the wrapping would remain long in place. Those articles so wrapped,have soon become exposed by the slipping of the wrapping material, thuspresenting a very unsightly appian'anw, and, what is more serious,permitting injury to the contents of the packil e.

'lhc object'of this invention is to afford a wrapping machine adaptedfor operation at hi h speed, to wrap annular objects with en)Stllllllilli uniformity, and to ap ly a continuous s irally woundcovering t iereon.

It is a so an object of the invention to afford an exceedingly simpleand compact device for the purpose specified, having a large range ofadjustment, to adapt the machine for wrap )ing annular bodies ofdifferent sizes, and in which the utmost facility for the insertion ofthe bodyto be wrapped, and the removal of the same from themachine afterthe wrapping, is attained.

it is also an object of the invention to provide means for positivelysupporting, and for rotating the body to be wrapped, and for adjustingsaid supporting and rotating means relatively to each other and thewrapping mechanism.

It IS an object of the invention also to afford an annular shuttle,having a reel of wrapping material mounted thereon, and

' means for rotating said shuttle through the eye of the annular body tobe wrapped,

while simultaneously rotating said annular body.

he invention embraces other important objects, as more fully hereinafterset forth. lhe invention (in a preferred form) is illustrated in thedrawings, and hereinafter more fully'deseribed.

Fig. 3 is an enlarged, sectional view, taken on line 3-3 ofig. 2, and with the belt pulleys shown in elevation. Fi 4 is an enlargedface view of the annu ar shuttle and i216 mechanisms carried thereon.Fig. 5 is an edge view of the same. Fi 6 is a section on-line- 6-6 of Fi4. lg. 7 is a fragmentary detail, part y in section, of a part of the.shuttle. Fig. 8 is an elevation of shuttle locking means. Fig. 9 is adelivery QItLGlBVittiOIl-Of the folding nozzle. Fig. 10 is--"' frontface view thereof. Fig. 11 is an enlarged face'view of the reel carrier.Fig. 12 is an enlarged, sectional view of the front adjustable guidepulley. Fig. 13 is a sectional view, with parts 1n elevation, of theupper or rear gui e and driving pulley for the shuttle.

As shown in the drawings: 1, indicates a relatively low base or table,supported upon a suitable frame or legs 2, and having a centrallongitudinal slot therethrough. Journaled transversely of said table onthe top thereof, is a driving shaft 3, having at the outer end thereof,a tight and a loose belt 7 is rigidly b0 ted to said table with the armsof the crescent directed upwardly and outwardly, or forwardly, as shownin Fig. 1.

Ri idly secured on said shaft 3, is a belt pu ley 7 having a peripheralflange 8, pro- ]ectin circumferentially on each face thereof, ,a 'ordinga grooved )eriphery for the belt 9. Journaled longitudinally of thetable on each side of sald belt pulley 7, in

, bearings 10 and 11, are shafts 12 and 13,

trained a sprocket chain 20, which also is trained about a sprocketwheel 21, journaled on the shaft 12, and integrally, or otherwiserigidly connected with the worm gear 22,

:also rotatably journalcd on said shaft and in mesh with a worm 23, onthe shaft 3, so

that the rotation of said shaft 3, by means of its tight belt pulley,acts through the medium of said Worm and worm gear and sprocket wheelsand chain, to rotate the rooved feed or advancing rollers 18. lileansare provided for adjusting said feed or advmuring rolls relatively tocachother. For this purpose, as shown, a downwardly directed arm 24, isprovided on each of said sleeves 14, and carried on the lower end ofeach is a nut 25, through which extends a screw shaft 26, pivotallymounted in a s'uitable bearing 27, therefor, secured upon the table 1,rotation of one of said screw shafts acting on the nut 25, to swing thecorrespending advancing or feed roll outwardly or inwardly, dependentupon the direction of rotation, thus enabling either or both of saidadvancin and feed rolls to be adjusted to the most efficient positionfor supporting and rotating or advancing the object to be wrapped.Outward adjustment of said feed rolls obviously permits the supportedobject to be supported somewhat lower in the machine, while inwardadjustment of the feed rolls supports said articles higher in themachine. Rotation of the shafts l2 and 13, because of the ecentricmounting thereof,

serves also to vary the tension on the corresponding'sprocket chain 20.Mounted on said rooved driving pulley 7, with its flat periphery fittingi the groove in the periphery of said iving pulley, is the annularshuttle 28, which is thus mounted transverselv of the tire or other bodyto be wrapped.

Extending through the forward arm of the crescent frame 6, at itsextremity, is a shaft'29, provided on the inner side of the frame with acollar 30, to bear against the face of the frame and at its outer endprovided with a nut 31, or-other means for rigidly securing the samefrom movement in the frame. Eccentrically connected with said shaft 29,at its inner end, or that 0p 0- sitethe nut 31, is a wrist pin 32, onwhich is journaled a peripherally flanged pulley 33, which may beconstructed in any suitable manner, or, as shown in Fig. 12, laid up inpart of sections of friction pa r or other suitable material 34. Said fliiilged alley is held in place on the wrist pin 32, iy means of suitablenuts or other releasable means 35. The other or rear arm of saidcrescent frame 6, at its extremity, is longitudinally slotted as shownin Fi 13, and extending through the slot is a ho t 36,

provided with a head 37, which bears against one side of said arm, whilesuitable nuts 38, as shown in Fig; 13, engage the other side thereof toclamp said bolt rigidly in adjusted position. A stud shaft 39, in-

tegral with said bolt, projects outwardly from the head thereof, andjournaled on said stud shaft is a, grooved belt pulley 40. Said grooved;pulleys 31 and 40, receive the periphery of the annular shuttle 28, inthe grooved facesv thereof, while said shuttle is supported on thegrooved driving pulley 7, thus engagin said shuttle at three points,

at substantially equal distances apart, and

permitting the shuttle to rotate freely therewith and therebetween. Abelt 9, trained ,about the grooved driving pulley 7, and the groovedpulley t0, also engages the periphery of the shuttle-28, for the entiredistance between thepulley 7, and said pulley 40, thereby acting torotate said shuttle. V A hinged section 41, is provided in said shuttleto permit the opening thereof for the insertion or removal of thearticle to'be wrapped. As shown, said hinged section is pivotallyengaged at one end on the end of the shuttle member 28, by means of apin 42, and at the other end is provided with a. projection 43 on bothsides theerof, adapted to receive the web 44, of the shuttletherebetween. A pin 45, extends transversely v through said projections,and is adapted to seat in aninclined'notch 46,115 shown in Figs. 4, 6,and 7, in the other end of said shuttle member, thus-insuring a. trueperiphcryfor the shuttle under all conditions when the hinged section isclosed, as shown in Figs. 4 and ,7. Means are provided for locking saidhinged section in closed position. For this purpose, as shown, a notchin the shuttle 28, indicated at X,'in Fig. 7. is provided at the innerperiphery thereof. and pivotally supported by means of a bolt 47,extending radially from the. inner side into said hinged section 41, ofthe shuttle is a swinging dctent 48. having a finger 49. adapted toengage in said notch. The elongated tail 50, of said detent extendsoppositely from said finger around the inner periphery of said hingedsegment. and pivotally mounted thereon is a lever 51, one end Lill in asuitable notch or recess in said iinge spring 53, engages the free endof said lever 51, and acts to hold the same normally in lockingposition, as shown in Fig. 4. hen it is desired to release the hingedsection, the tail of the lever is pressed downwardly to the tail 50, ofthe detent, thus releasing the locking end of the lever, whereupon theever may be swung laterally, carryirgg the finger 49, thereon out of thenotch and permitting the shuttle to he opened. Mounted on the face ofsaid shuttle at the side opposite the cresceut frame 6, ahddiametrically opposite the hinged section of the shuttle is an inwardlyand laterally inclining stud shaft 54, and provided, as shown, with aface plate or co lar 55, rigidly secured thereon. Said stud shaftextends upwardly through the collar or hub 56, of said collar or faceplate, as shown in Figs. 4 and 11.

Said hub is of a diameter to fit in the here or core in a paper reel 57,having the paper or other wrapping material) 58, wound t ereon, as shownin Figs. 1, 2, 4, 5 and 11, and secured on the upper end of said huh,and extending peripherally, but eccentrically around the same, are erings 59, each at its free end provided wit an outwardl extending andslightlv inwardly incline projection 60, adapted when the reel of wrap-)ing material is pressed thereover, to spring inwardly to permit thereel to receive the hub therethrough with said springs engaging over theouter face of the reel to hold the same from displacement and affordtension. Mounted upon a bracket 61, pivotally and obliquely secured uponthe face of said reel, is an edge turning or folding device 62,comprising a sheet or plate of metal bent to afford a tapering nozzle63, comprising an narrow fold, an outer inner and relativel lip 64,integral with the wider fold, and a outer fold, and turned over theinner. The opposite. end of said nozzle is wider and.

flaring to receive the paper and other material therein, as shown inFigs. 4 and 5. Said nozzle is secured on the bracket 61, in any suitablemanner, with the tapered end thereof directed outwardly and adjacentsaid tapered end, and set in the face 'of the shuttle, is a stud shaft(i5,that is ap )roximately parallel with the stud shaft 54. Journaled onsaid stud shaft, is a roller (36,

or, if preferred, the stud shaft may be providcd merely with, a roundedor convex face over which the paper, or other wrapping material, may. bedrawn to set the fold therein and to direct .the strip suitably to thearticle to be wrapped.

Mounted upon the table at the rear of the shuttle, and rigidly securedin a bracket (37, is a standard (38, and adjustably secured on saidstandard in any suitable manner, is a yoke 69, having journalcd betweenits arms and against which t 0 top of the tire, or other annular body tobe wrapped, rests,

and travels during the wrapping operation.

The operation is as follows: The machine is first adjusted to the sizeof the annular bodies to be wrapped, and this is accomplished byadjusting the advancing or feed- 1ng rollers 18, inwardly or outwardlytoward the shuttle by means of the screw shafts 26. The yoke 69,carrying the roller 70, is then adjusted upwardly or downwardly on thestandard, and outwardly or inwardly, as required, to properly supportthe top of the annular body, as indicated in dotted lines in Fig. 1. fnot previously satisfactorily adjusted, the grooved rollers 33 and 40,are adjusted to bear upon the periphery of. the shuttle, and togetherwith the grooved pulley 7, afford three points of contact and supportfor the shuttle, between which the same is rotated, said shuttle, ofcourse, havin frictional engagement with the grooved riving pulley 7,the grooved roller 40, and one run of the belt between .may rotatethrough the eye of the other.

The driving belt now being shifted to the tight pulley, the shuttle isrotated at a rela tively high rate of speed, while the tire is rotatedby means of the advancing rolls 18, at a suflicient rate to give thedesired lead for the material wound upon the tire or coil, while thepaper or other wrapping material, is drawn from the reel through thefolding nozzle 62, around the'guide arm or roll 66, and thence, by therotation of the shuttle, is wound about the tire. The operationcontinues until the annular body is fully wound or covered, the drivingbelt is then shifted to the loose pulley, the machine stopping almostinstantly, the shuttle again opened, and the annular body removed andanother inserted, whereupon the operation is repeated. When it isdesired to replenish or to renew the paper reel, the extended ends 60,of the retaining springs on the hub 56, are pressed inwardly, thuspermitting the core of the reel to be removed and another reel or rollof paper to be inserted thereon.

Details of the construction may. of course, be varied through a widerange. I have, however, shown and described but a preferred form of myinvention, although numerous details of construction and operation willreadily suggest themselves. I
